DRILL & TAPPING CHART

AHOLD ORIGINAL THICKNESS

WEB THINNINGOn most drills the web increases in thickness towards the shank with the result that, as the drill is shortened by repeated sharpening, the chisel edge will become wider.As the chisel edge does not cut but forces the metal out of the way, too wide a chisel edge will result in more pressure required for penetration, leading to greater heat generation and a resultant loss of life.

CUTTING FLUIDSThe use of cutting fluids is an advantage in most drilling operations and essential in some. The two main functions of the cutting fluid are lubrication and cooling.The purpose of lubrication is to reduce friction by lubricating the surfaces tool and work, to facilitate easier sliding of the chips up the flute and to prevent the chips welding to the cutting edges.In production work, particularly when drilling deep holes, the cooling action of the fluid is often more important than the lubrication. Overheating will shorten the life of the drill.Intermittent feed on deep holes, where possible, not only clears the chips but permits more effective cooling.

SPEEDSThe speed of a drill is the rate at which the periphery of the drill moves in relation to the work being drilled.As a rule, with a drill working within its speed range for a specific material, more holes between sharpenings will be achieved if the speed is reduced and less holes if the speed is increased. Thus, for each production run, a speed must be established which will result in the highest rate of production without excessive breakdown time or drill usage. The factors governing speed are: Component material, hardness of material, depth of hole, quality required, condition of drilling machine, efficiency of cutting fluid.

FEEDSThe feed of the drill is governed by the drill size and the component material.As with speeds, an increase in feed will lessen the number of holes produced sharpening but it is essential that a constant feed be maintained. If a drill is allowed to dwell, breakdown of the cutting edges will result.

SMALL DRILL FEEDS AND SPEEDSBreakdown of small drills can most often be attributed to two faults: speed too high and feed too low.A feed which will produce CHIPS not POWDER, coupled with a speed compatible with the strength of the drill is essential for small hole drilling. Feeds must be based on thickness of chip, not mm/min, and speeds adjusted accordingly. ExAMPLE: A 1mm drill is to operate at a feed of 0.013mm /rev, drilling steel.While the material may permit a speed of 30m/min or 9,500 RPM it is obvious that the drill could not withstand a load of 0.013mm feed at this speed; a penetration rate of 124mm/min. The correct procedure is to retain the feed but reduce the speed to obtain a penetration within the capacity of the strength of the drill.

DEEP HOLE DRILLINGWhen drilling deep holes, speeds and feeds should be reduced as follows:

6 to 8 times drill diameter 35 to 40 20

BLACK JET/BLUE BULLET JOBBER DRILLSEvacut “Black Jet” and Sutton “Blue Bullet” jobber drills provide ultimate performance and value for money. You get 2-3 times more life when drilling ferrous materials e.g.: stainless steel, high tensile steel, alloy and tool steels and cast iron.

What is the difference: a ferric-oxide (Fe2O3) surface coating improves heat dissipation, lowers friction and reduces material build up on the cutting edge, hole accuracy and size is improved in production applications and provides longer tooling life at the same feeds and speeds of conventional bright drills.

SILVER/BRIGHT FINISH JOBBER DRILLSThe silver or bright finish jobber drills are made from the same quality material as the Black Jet/Blue Bullet drills. The shiny smooth surface finish makes them more suited for repetitive drilling in non-ferrous material like aluminium and brass when the softer sticky material can bind to the cutting edge.

* Tool life and finish quality will be increased by using a suitable coolant/lubricant

THE BODYThe portion of the drill extending from the extreme cutting end to the commencement of the shank.

BODY CLEARANCEThe portion of the body reduced in the diameter to provide diametrical clearance.

CHISEL EDGE ANGLEThe obtuse angle between the tangent to the projection of the chisel edge axis and the projection of the line through either outer corner and corresponding chisel edge corner on a plane normal to the drill axis. This angle lies in a plane normal to the drill axis.

DRILL DIAMETERThe measurement across the cylindrical lands at the outer corners of the drill.

FLUTE LENGTHThe axial length from the outer corners of the cutting lips to the extreme back end of the flutes, including point.

HELIx ANGLEThe acute angle between the tangent to the helical leading edge of the flute at a point in this edge and a plane containing (drill and helix) axis and the point in question. This angle lies in a plane normal to the radius at the point on the edge. The helix angle is usually measured at a point close to or coincident with the outer corner.

LIP CLEARANCE ANGLEThe acute angle between a plane normal to the drill axis and the tangent at a point on the lip to the drill flank, in a plane normal to the radius at the point in question. This angle is specified and measured at the outer corner.

LIP LENGTHThe minimum distance between the outer corner and the chisel edge corner or inner corner. (For a straight lip, it is the true length of the lip).

POINT ANGLEThe included angle between the projections of the lines joining the outer corners and the corresponding chisel edge corners on a plane parallel to one (or both) of these lines and the drill axis.

WEB (CORE) THICKNESSThe diameter of the circle normal to the axis through the roots of the flutes at the point end of the drill.

FLUTESThe grooves in the body of the drill which provide lips and permit the removal of chips and allow cutting fluid to reach the lips.
